also barney is purple. the count is purple on sesame street but not a purple dinosaur. plus he does basically what the whole sesame street does but as one person. he teaches the same things, education, life lessons, and how to behave.

Some say that "Sesame Street" and other children TV shows that show images for less than one second at a time, is partially to blame for the rise in ADHD diagnoses. The show is broken into 40 short, unrelated segments — the sort of pacing that arguably triggers attention-deficit problems. Images move to quickly and kids can't process that fast!!
